Cost effective Schumann Resonator


After reading about the Acoustic Revive unit, I was looking on Ebay and found a Schumann Resonator for $175 (plus $20 for a very nice plexiglass case). It's model designation is Chartres Mk.2. It is made by a fellow named David in Indonesia. He was a pleasure to deal with, start to finish. The unit arrived in about 10 days. The fit and finish was reassuring. It is a circuit board with good quality components mounted between two sheets of well cut and finished plexiglass.
I have read, and failed to understand a lot that has been written about Schumann resonators, but I am willing to. Suspend disbelief and try a tweak that a lot of folks say works. My initial reaction on hooking up the resonator was disbelief. Sound stage and localization were noticeably better. I had to disconnect and reconnect the unit several times to convince myself that I wasn't fooling myself. Mechanism of action be hanged, it made a very positive difference in my system. This finding was confirmed my moving it to a second system where, again, spatial information seemed much improved.
I am very happy with this purchase. Results rule!

You send me some  Thanks....But I add the shungite to it  ….A good idea... I thank you very much for your kind gift....My best...
So, are you using two shungite plates for the USB devices yet? Squeeze those photons!! Squeeze ‘em real good!
I will try... But Geoff you had another brand of Shumann Generator than me I think a rectangular black like a key....... Probably better... I think it is possible with these to put 2 small plate shungite+copper on each side of the S. G. … Mine are not those rectangular thin usb S.G. ...I will try after buying the rectangular Ufeel ...
Maybe you need to get one or two of the very accurate BLACK USB Schumann device from Hong Kong. Hmmmmmm....🤔
You are right....Perhaps because you are from the future.... :)


Do you know that Terence Tao has given the first long waited attempt to the Collatz conjecture? Not a solution tough....This is a very big mystery, because the problem can be stated to a child and Paul Erdos said mathematics are not yet ready for this problem.... Fascinating.... My best...
Yes, that’s correct, I’m from the future. But sadly it’s not everyone’s future. It’s only my future, just like my past. Fortunately, my iPad forwards messages to me in the future. I have a special app. By the way, the future is not that great. There are no more audio forums. They were unable to control the cable debates which got really crazy. So now I have to come back here for all the jokes. The other weird thing, in the future everything is McDonalds. They now have a Trillion Trillion Big Macs sold. 🍔
This is my favorite spirit line of yours.... Indeed thanks....

Me I will go back to the abyss of the prime series....
I see the seller on Ebay named David like OP mentioned. Is he someone that makes solid Schumann's?
You pays your money and you takes your chances. I think the BLACK USB little finger size SR from Hong Kong is a good deal. 
Thanks. Pic 5 shows this usb device plugged into an ac usb adapter into a wall outlet. My understanding from reviews is that SR should be approx 5-6 feet above the floor for best effects. Does this make a difference?
I use a USB wall wart and six-foot long USB cable so that the device can be suspended more than 1m50cm off the floor. Better safe than sorry.
I took the plunge and bought two Chinese units from ebay a couple of days ago. They won't arrive until March. Curiosity finally got to me.
